From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]
Plant Biol (Stuttg)Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]
Am J BotAbstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Scaphyglottis cobanensis (Orchidaceae, Epidendroideae), A New Species from Guatemala
Polish Botanical Journal, 2016 Abstract Scaphyglottis cobanensis Archila, Szlach. & S. Nowak (Orchidaceae, Epidendroideae) is described and compared with the morphologically close species S. bifida (Rchb. f.) C. Schweinf. and S. lindeniana (A. Rich. & Galeotti) L. O. Williams. The new species is illustrated with SEM images of the labellum and gynostemium.

Seven New Complete Plastome Sequences Reveal Rampant Independent Loss of the ndh Gene Family across Orchids and Associated Instability of the Inverted Repeat/Small Single-Copy Region Boundaries. [PDF]
PLoS ONE, 2015 Earlier research has revealed that the ndh loci have been pseudogenized, truncated, or deleted from most orchid plastomes sequenced to date, including in all available plastomes of the two most species-rich subfamilies, Orchidoideae and Epidendroideae ...

Complete Chloroplast Genome of the <i>Eria</i> Sensu Lato Complex (Orchidaceae): Comparative Analysis and Phylogenetic Relationship. [PDF]
Ecol EvolWe sequenced and assembled 18 complete chloroplast genomes representing the Eria sensu lato complex. Our comparative analyses unveiled stepwise NDH complex degradation, lineage‐specific positive selection on ycf1, and climate‐driven rapid radiation during the Late Miocene.

Four New Species of Adeneleuterophora (Orchidaceae, Epidendroideae) from Colombia
Polish Botanical Journal, 2013 AbstractFour new species of the orchid genus Adeneleuterophora Barb. Rodr. are described and illustrated, based on Colombian material: A. orozcoi Szlach. & Kolan., A. magnipetala Szlach. & Kolan., A. luteyni Szlach. & Kolan. and A. Szlach. & Kolan. emberana. Their taxonomic affinities are briefly discussed.

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of "double deception" in fully mycoheterotrophic plants. [PDF]
Am J BotAbstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.

Oncidiinae (Orchidaceae) on the great curve of the Xingu River, Pará state, Brazil [PDF]
Brazilian Journal of Biology, 2015 Among the studies on Orchidaceae in the Amazon, none comprised the region of the Great Curve of the Xingu River, located in the lower Xingu river. The aim of this study was to inventory and taxonomically study the species of Oncidiinae (Orchidaceae) in ...

Target sequence capture in orchids: Developing a kit to sequence hundreds of single‐copy loci
Applications in Plant Sciences, 2021 Premise Understanding relationships among orchid species and populations is of critical importance for orchid conservation. Target sequence capture has become a standard method for extracting hundreds of orthologous loci for phylogenomics.
